The performance and implementation of the method of wealth management, the present invention also contains '= kind of change order' and (d) fall in the spirit of the invention. Among them. 1A 1B and 1C are functional block diagrams of a general application of a removable electronic device in accordance with an embodiment of the present invention. The electronic device, 30 (probably called Mu card) can support compatibility with Cong and mmc, cf (small, flash), (smart media), and SD (secure digital) applications. &quot; The mode of operation of the person. For example, the USB compatible mode includes a USB 2.0 application, while the MMC compatible mode includes one of an MMC 4 〇 or MMC SPI (serial-to-peripheral interface) application. For the sake of simplicity, only the MMC compatibility mode is set forth in the following (d) embodiment. Those skilled in the art will appreciate that the invention is equally applicable to modes such as CF, SM, SD, and the like. The electronic device 3G includes a -1, 4, 8, or 16-bit interface, and provides low voltage support of 5V/3.3V/1.8V, and has zero power consumption during standby. In addition, the electronic device 30 can support about 5 〇. Width bandwidth from kb/s to 120MB/s. Conversely, MMC4.0 support - ! 4, or 8 bit data transmission, the maximum speed is 52 MB / Sec; and USB 2.0 supports data transmission with a maximum speed of 60MB / SeC. As a result, the electronic device 3 can provide high-level applications while retaining at least the reverse compatibility capabilities associated with applications such as USB, MMC, and MMC SPI. Figure 1A is a functional block diagram of an electronic device 3A operating in a USB mode. Referring to FIG. 1A, the electronic device 30 includes an interface (IF) mode detector 32, a multimedia card (MMC) device controller 34, an interleaver %, and a 12 1289313 serial bus (USB) physical layer. A (PHY) circuit 36, a USB device controller 37, and an application module 38. When the electronic device 30 is inserted into the host 40, the IF mode detector 32 detects the operation mode for distinguishing between the MMC mode, the USB mode, or the Mu mode. Host 40 (for example, a laptop, PC (cell, phone, tablet, personal digital assistant, or digital video camera (DV) / digital camera (DSC)) may contain a card reader (in the picture) Not shown) for accommodating the electronic device 30. In this embodiment, the IF mode detector 32 detects whether the host 40 (connected to the electronic device 30) conforms to the USB specification. The USB device controller 37 transmits the USB PHY. The circuit 36 controls the data transmission on the common bus 42 between the host 40 and the application module 38. The application module 38 depends on the operation mode of the detected column and can be used as a memory or an input/output (I/O). Figure 1B is a functional block diagram of the electronic device 30 operating in the Mu mode. Referring to Figure IB, the IF mode detector 32 detects whether the host 40 (connected to the electronic device 30) conforms to the Mu specification. The device 37 controls the data transfer between the host 40 and the application module 38 via the interleaver 35. The interleaver 35 interleaves a call to a function or program within another function or program, the interleaver 35 will be 16 bits Convert metadata into USB device controller 37 The identified serial data, or reverse conversion. In this regard, the interleaver 35 bridges the Mu bus between the busbar and the UTMI (USB 2.0 Transceiver Macrocell Interface) bus. The interface specifications developed to define the physical layer circuits of USB 2.0 and some of the logic layer circuits can contribute to a data transfer rate of 480 Mbps in high speed (HS) mode, which is much higher than USB 1.1 13 1289313 The rate can be kept backwards compatible with the USB 1.1 standard. Figure 1C is a functional block diagram of the electronic device 30 operating in the MMC mode. Referring to Figure 1C, the IF mode detector 32 detects the host 40 (and Whether the electronic device 30 is connected to the MMC specification. The MMC device controller 34 controls the data transfer between the host 40 and the application module 38. The MMC application includes one of the following: MMC 4.0, 1, 4, or 8-bit interface Or MMC SPI, 1-bit interface. Figure 2 is a flow chart of a method for detecting an operation mode according to an embodiment of the present invention. Referring to Figure 2, at the device end, the host 40 is turned on at step 50 (and Electronic device 30 connected) The power supply voltage VDD of the host 40 is detected at step 52 to determine whether VDD is equal to or greater than the voltage level required by the USB application. Typically, the USB application can operate at a voltage level range of approximately 4.5V (volts). ) to 5.5V, and the voltage level criterion that the MMC or Mu application can operate is about 1.8V or 3.3V. In one embodiment, if the VDD level of the host 40 is equal to or greater than 4.4V, then At step 54, the mode of operation is determined to be USB 2.0. If the VDD level of the host 40 is less than 4.4V, the mode of operation is determined to be a Mu application or an MMC application. Next, at step 56, it is determined whether the command signal CMD0 sent by the host 40 is received by the electronic device 30. At step 58, the command signal CMD0 is detected during the preset time period. If the preset time is exceeded, at step 60, the host 40 will be turned off or "suspended" to save power. If the preset time is not exceeded, the command signal will continue to be detected. When the command signal is received, it will be judged at step 62 that the command signal 14 9313 is long and the factory is applied. If the command signal is not the decision of the MU command signal, it is determined that the operation mode is the MMC application. If the MU 薏 3 〇 P 4 4 MU command signal, at step 66, the electronic will respond to the host 40 in the operation mode as the Mu application. Then, it is said that the eight electronic devices 30 will wait for a preset time (for example, the host whispering clock) to synchronize. In general, the clock rate is dependent on the system clock. Next, at step 70, the electronic device 30 maps to the Mu interface to facilitate the mu application at the step. The method is another flow chart for detecting an operation mode according to an embodiment of the present invention. Referring to FIG. 3, on the host side, the master sample 40 sends a -Mu command signal MuCMD0 to the electronic device 3 at step. At the main frame 82, if the electronic device 3 does not send a response signal, a message VIMC command signal MMC D〇 ' is sent at step 84 to indicate that the operation mode is an MMC application at step 86. At step 82, if the electronic device 3 replies with a Mu response signal, the host 40 transmits a predetermined number of clocks (for example, 8 clocks) at step 88 for synchronization. The electronic device 30 will switch to the Mu mode at step 90. At step 92, the electronic device 30 can optionally send a signal to the host 40 to indicate that the Mu interface is ready for use. For example, the command signals MMCCMD0 and MuCMDO are defined as the following 6-byte format "40h, 00h, 00h, 00h, 00h, 95h" and "40h, 4Dh, 55h, BFh, B2h, AAh", respectively. Furthermore, the Mu response signal is defined as the following 6-byte format "19h, [4-byte operation parameter], FFh". 15 1289313 Figure 4A is a perspective view of a pin configuration of a removable electronic device in accordance with an embodiment of the present invention. Referring to Figure 4A, all of the contacts at the device end remain in the HiZ (high impedance) state until the mode of operation between the host and the removable electronic device is determined. For the MMC4.0 mode, the first pin (ie, DAT 3) of the 玎-removable electronic device is defined to switch the MMC4.0 mode to the MMC SPI mode, which is defined in the MMC specification. in. The second pin of the Mu interface mode (i.e., DAT 8) is used to confirm the selected MMC mode or Mu interface mode. USB Mode • The fourteenth and fifteenth pins (ie, D+ and D-) are a pair of data signals that can be used to determine if the USB mode is selected. The pair of data signals (D+, D-) are a complementary pair, wherein when one of them is at a high level, the other is at a low level. For SIMM (single row memory module) card applications, pins 18, 19, 20 are retained. Thus, the removable electronic device of the present invention is capable of supporting MMC compatible applications, USB compatible applications, and Mu interface applications while retaining the flexibility for SIMM applications. An example of the interface protocol of the present invention is as follows: 1 · SYNC block' (1) 1-bit: DAT: Ob (2) 4-bit: 〇八丁1&gt;.0;|=^-like (^ (3) 8-bit: DAT[7:0] = xxxxxxxOb (4) 16-bit: DAT[15:0] = xxxxxxxxxxxxxxxOb where "X" indicates conditions unrelated to the agreement.
